In Toronto, Ullmark had the task of standing up to his goal-scoring compatriot William Nylander, something he managed with honor.
Neither Nylander nor his teammates were able to get past Ullmark, who saved 27 shots and kept a clean sheet for the first time since he left Boston for Ottawa before the season.
It's always great to win, regardless of who you meet, says the 31-year-old to reporters after the match.
The win was much-needed for the Canadian team, which has had a hard time winning on the road.
Florida had won seven matches in a row before the home game against New Jersey. But an eighth win did not materialize. Instead, the visitors took home the win with 4–1 after 34 saves by Markström. New Jersey's Jesper Bratt is credited with two assists.
